Gilberto Gil, recently named as Brazil's minister of culture, has always trodden a very individual path in Brazilian music. But even by his own standards, this is an unusual work. The Zumbi of the title is a Brazilian hero. He founded Palmares Quilombo, a place in Brazil where escaped and freed slaves could live as they had in Africa. Until closed by the Portuguese, Palmares Quilombo lasted almost 100 years. Z is a celebration of the man, conceived as a ballet, celebrating the 300th anniversary of Zumbi. The music here is actually a collaboration between Gil, the great songwriter and musician Carlinhos Brown, and Rodolfo Stroter, who was musical director for the project (however, the album appears under Gil's name).
